Transient Voltage Suppressors (TVS) are commonly referred to as surge protection devices. They are semiconductor components designed to protect a variety of electronic equipment from electrical overstress (EOS) due to induced electrical transients. When transients occur, these components will shunt the excess energy through them, limiting the voltage that is supplied to the equipment. TVS – Varistors and MOVs are two types of TVS.

B72205S0600K111 is a varistor. The letter “B” means radial leaded, the number “7220” is the voltage rating, “S” is the product series, and the number “600K” represents the maximum clamping voltage. Varistors have semiconductor, non-linear junctions that can be used to protect against surges and transients. Varistors absorb the excess current and dissipate it as heat, limiting the current flow into the equipment.

The application fields of B72205S0600K111 are mainly communication systems, computer, consumer electric equipment and other industrial equipments which requires surge protection. It is especially suitable for applications with lightning and voltage surge. B72205S0600K111 is designed to protect against transient overvoltage. It is capable of diverting high levels of energy from short duration, high intensity transient overvoltages and is designed to dissipate large pulses of energy.

The working principle of B72205S0600K111 is based on the principle of avalanche breakdown. It is made up of two semiconductor junctions set in opposition to one another, called PN junctions. When a voltage greater than the breakdown voltage is applied to the junction, it will cause current to flow in the form of electrons and holes through the PN junction. The excess current will be diverted away from the protected equipment and dissipated as heat.

B72205S0600K111 has several advantages compared to other TVS. Firstly, its operating voltage is much lower than that of a conventional MOV, allowing it to operate at lower voltages. Secondly, its response time is very fast, allowing it to protect against transients in real time. Additionally, it has a low leakage current and a low clamp voltage, making it suitable for a wide range of applications. Finally, it is much more reliable than an MOV and can handle more voltage and energy spikes.

In conclusion, B72205S0600K111 is an efficient transient voltage suppressor designed for surge protection of a variety of electronic components. It works by diverting high voltage from transient overvoltages and dissipating them as heat in order to protect the electronic equipment. It is a cost-effective alternative to a conventional MOV with better performance. It has a low leakage current, fast response time, low clamp voltage, and is suitable for a wide range of applications.
